HID: add driver for Roccat Kone gaming mouse
This Patch adds support for Kone gaming mouse from Roccat. It provides access to profiles, settings, firmware, weight, actual settings etc. through sysfs attributes. Event handling of this mouse differs from standard hid behaviour in that tilt button press is reported in each move event which results in strange behaviour if not handled by the driver. This is a heavily reworked version of the previously introduced driver. The changes include most of the previously raised concerns, memory leak and other fixes, code cleanups, adoption of additional achieved knowlege about the hardware and is (IMHO) a much better version than before even when I exchanged reduced USB-IO with a bigger memory consumption. I refused to implement one mentioned point: Removing the 'just-because-we-can' attributes. Motivation: Reading the clipped in weight: I'm no gamer and can't determine the usefulness of this feature but if the manufacturer implements such a feature it might make sense to someone and I would unwillingly limit the functionality besides its such a small feature. Reading the actual profile and dpi settings: Here I can testify that one can get lost of the actual settings when switching back and forth. The manufacturers windows driver has the ability for on-screen-display of the values and there is a mouse in the market that has an lcd on the underside of it to show these values. So I think this feature makes sense not only for me and shouldn't be removed. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

+ When read, this file returns the raw number of the actual dpi

+Description: When read, this file returns the raw integer version number of the
+ firmware reported by the mouse. Using the integer value eases
+ further usage in other programs. To receive the real version
+ number the decimal point has to be shifted 2 positions to the

+Description: When read, this file returns the driver version.
+ The format of the string is "v<major>.<minor>.<patchlevel>".
+ This attribute is used by the userland tools to find the sysfs-
+ paths of installed kone-mice and determine the capabilites of
+ the driver. Versions of this driver for old kernels replace
+ usbhid instead of generic-usb. The way to scan for this file
+ has been chosen to provide a consistent way for all supported
+ kernel versions.

+Description: The mouse can store 5 profiles which can be switched by the
+ press of a button. A profile holds informations like button
+ mappings, sensitivity, the colors of the 5 leds and light
+ effects.
+ When read, these files return the respective profile. The
+ returned data is 975 bytes in size.
+ When written, this file lets one write the respective profile
+ data back to the mouse. The data has to be 975 bytes long.
+ The mouse will reject invalid data, whereas the profile number
+ stored in the profile doesn't need to fit the number of the
+ store.

+Description: The integer value of this attribute ranges from 1 to 5.

+ that's active when the mouse is powered on.
+ When written, this file sets the number of the startup profile
+ and the mouse activates this profile immediately.

+Description: The mouse has a "Tracking Control Unit" which lets the user
+ calibrate the laser power to fit the mousepad surface.
+ When read, this file returns the current state of the TCU,
+ where 0 means off and 1 means on.
+ Writing 0 in this file will switch the TCU off.
+ Writing 1 in this file will start the calibration which takes
+ around 6 seconds to complete and activates the TCU.

+Description: The mouse can be equipped with one of four supplied weights
+ ranging from 5 to 20 grams which are recognized by the mouse
+ and its value can be read out. When read, this file returns the

+ in other software.
